Feature Request: add an offline mode. #50

Yes, this is something I do want to do! Ive been saying for a long while that ill do it, but havent gotten around to it just yet. One limitation is that it would still require a network connection to download stuff that isnt ours (minecraft its self). Would this be an issue for you? or do you already have the minecraft jar? |
No, it is perfectly fine for Nix to have minecraft jar and whatever resources on the Internet. The only limitation Nix has is that no Internet should be available during build/install phase. |
This answer confuses me. What we from nix want is to have a directory where we can put things like the minecrat.jar, and give this directory to fabric installer, which then has no way of connecting to the internet. |
I was also looking into adding fabric support to nixpkgs today. Good to know this is on someone's radar already. Fabric devs, feel free to ask any questions.
The steps in nix would be something like:
Nix will download these files from the url humans give it, and will check that the file matches a human provided checksum.
fabric-installer should yell about missing files and such but can't ever access the internet. |
I am about 1/2 way through the changes. I will comment on this issue once I have something ready to test. |
Hey Ive been looking into this again, is there any information you might need? Not to rush or seem demanding in any way. Alternatively if you don't think this will get added, maybe could point me to some information on how to manually install fabric without the installer? Thanks |
any updates? |
Specifically for nix there is one option available. Created by someone who wants to minimize their internet presence, and updated/changed a little by me:
{ callPackage, writeTextFile, writeShellScriptBin, minecraft-server, jre_headless }:
let
loader = callPackage ./generate-loader.nix {};
log4j = writeTextFile {
name = "log4j.xml";
text = ''

} while this is a package you can just swap into the minecraft-server module, it's a little bit cursed... So I'm hoping to get a better solution at some point as well. |
i have no idea whats "nix" and i dont use it |
this is only about nix so why are you asking about it 😂 |
oh ok for some reason online-mode setting is ignored on my server (its always on) |
Has there been any updates on this? @modmuss50 @dali99 |
While this doesn't solve the problem at the root of this issue, I've gone ahead and packaged (pretty much) all versions of Fabric servers for Nix here: https://github.com/Infinidoge/nix-minecraft If an offline mode is added, that would make the packaging much easier, though. |
Hi, I am a packager for NixOS (https://www.nixos.org), and I am trying to package the fabric loader (specifically server side) here.
However, due to the certain constraints from NixOS packaging process, there would be no network during it.
I am wondering if all other parts like vanilla server are present, how can I force installer not to access Internet?
Or, can we have an offline mode?
Thanks in advance!
